Answer:
25.2 grams HOAc
Explanation:
For solution preparations a simple formula for determining amount of solute needed is ...
from solid stock => grams = Molarity x Volume (Liters) x formula wt of solute
∴ grams HOAc = M·V·f.wt = (0.839M)(0.500L)(60.05g/mol) = 25.2 grams HOAc
Mixing => Transfer gram wt of solute to mixing container and dilute up to but not to exceed total needed volume.
Answer:
n = 0.413moles (3 sig-figs).
Explanation:
From definition of molarity, solve for moles and substitute given data.
Molarity(M) = Moles Solute(n)/Volume of Solution in Liters(V)
M = n/V => n = M·V => 0.330moles/Liter x 1.25Liters = 0.4125moles ≅ 0.413moles (3 sig-figs).
Close to about -36 degrees Celsius ( - 33 degrees Fahrenheit) in January but can drop to -60 degrees Celsius ( - 76 degrees Fahrenheit).
in July, it can be close to -19 degrees Celsius (- 2 degrees Fahrenheit)
Hello! The reactions are catalyzed, or sped up by enzymes. Enzymes have strict conditions they can work under, including a small range of temperature. Temperature increase slows the rate of reaction, and extreme temperature increase can denature, or destroy an enzyme. Hope this helps! :)
